Based on last year's onion
experiments, I've
decided to start my storage onions inside this winter. The other
option that worked well was to grow the onions under quick hoops in
soil doctored with biochar, but I only have one bucket
of the precious amendment and am not sure I want to "waste" it on
onions. (My quick hoops are all full of overwintering greens
anyway.)
So I headed out to the
old apple tree for some stump
dirt to use as
potting soil. I put the stump dirt directly into my seed starting
flats, wet it down, then lightly compressed the organic matter with my
fingers. After sprinkling seeds on top, I added a thin layer of
composted horse manure --- sometimes I use stump dirt alone as
potting soil, but the apple tree's rotted center didn't seem quite as
dark and rich as the organic matter I mine out of the beech tree
further away.
Assuming they come up
and grow, I'll transplant tiny onion sets at the beginning of
March. Although it seems rough to throw them into unprotected
ground so early, last year's transplants did find even without a quick
hoop. Maybe 2012 will be the year we finally delete the last
storebought vegetable from our diet?
Great question. Part of it is just that I'm lazy --- Egyptian onion bulbs rarely get more than an inch in diameter, and that's a lot of work to peel a cup or two of onions that I use in most dishes.
But it's also a matter of taste. I think Egyptian onions don't taste like storage onions. They're a little less sweet and a little more bitey --- a bit like a mix between onions and garlic. So I like the sweet storage onions when cooking certain dishes.
I hope that potato onions may one day fill that niche, but I'm still experimenting with getting them bigger than Egyptian onions....
